DISTRIBUTING DEVICE FOR GRAIN-DRILLS.

Specification of Letters Patent.

Patented. Jan. 22, 1907.

Application filed August 3, 1906. Serial No. 328,985.

To all whom it may concern:

Be it known that we, FRANK R. PACKHAM and GEORGE P. OATES, citizens of the United States, residing at Springfield, inthe county of Clark and State of Ohio, have invented certain new and useful Improvements in Dis- 'tributing Devices for Grain-Drills, of which the following is a. specification.

Our invention relates to grain-drills, particularly t0 grain-distributing devices therefor.

The object of the invention is to provide a simple and comparatively cheap structure in which the distributing-wheel in addition to its usual. function will serve as a mechanical agitator, operating by its rotation to prevent the bridging of fibrous bearded grains.

It has been found in practice that certain bearded grains, such as oats of the rust-proof variety, and some varieties of .rice by becoming interengaged in the hopper tend to bridge or arch and. support the grain above, thus preventing it being fed through the distributing device. To prevent such bridging or arching is the primary object of the present invention.

A further object is to provide means for advancing or expelling the measured grain which, owing to the above-mentioned peculiarity, lingers in tnemeasuring-channel, and thus greatly increasing the accuracy of the sowing.

With the above primary and other incidental objects in view, as will appear from the specification, the invention consists of the construction, the parts, the combination, and arrangement thereof or their equivalents, hereinafter described, and setforth in the claims.

In the drawings there is shown a distributer of the double-hopper variety having a single distributing-wheel adapted to receive. grain upon either side, the one side of said wheel being plain, as ordinarily constructed, while the other side is provided with the mechanical. agitating means which forms the subject of the present invention.

In the drawings, Figure 1 is a perspective view of the distributing device with one of the hoppers removed to show the side of the distributer-wheel provided with the agitating device for the bearded grain. v spective view from the rear or discharge side of the distributer.

'ed to grains of different kinds.

Fig. 2 IS a per Fig. 3 is a perspective view of the distributer with one of the hopper members removed andthe distributer-wheel partly broken away to show the recess in the opposite hopper, through which the agitatingstuds move. Fig. 4 is a vertical sectional View ofthe device, the section being taken on a line through the center of the hub of the dis tributer-wheel, as indicated by the line :13 as in Fig. 3, both halves of the casing, however, being shown in the view, the view being one looking to the right of Fig. 3.

Like parts are represented by similar characters of reference throughout the several views.

Referring to the drawings by letter, a a re resent the hopper members, within which is located the revoluble distributer-Wheel b. Extending over the distributer-wheel Z) and engaging with the opposite sides of the hopper members a a; is a bridge-piece c, conforming substantially to, the periphery of the distributer-wheel b and adapted to form the lower edge of a partition in the grain-box of the drill. The distributer-wheel b is provided' with flanges I), having on the interior thereof a series of ribs 6 which serve to carry the grain from the hopper a through the distributingchannel a, formed in said hopper members a, and to discharge the same outside the distributer structure. The opposite sides of the distributer b are preferably adapt- Projecting from the Web of the distributer-wheel b and located at points intermediate the center and flange are one or more studs or fingers 6 As the distributer-wheel rotates the fingers b engage with and agitate the grain within the hopper a and prevent the grain from becoming interlocked, so as to retard the flow of grain through the device. preferably arranged in such relation to the flange b that as. they rotate they will pass out of the hopper member a through the measuring-channel a, as shown in Fig. 2 thus assisting in the discharge of the grain through said measuring-channel and preventing the bearded grain becoming interlocked therein. Upon continued rotation of the distributer-wheel b the studs or flanges 6 again enter the hopper member a througha suitable groove or recess a. in the wall of said hopper member a, as shown in Fig. 3. It

The studs b are.

will be seen that there is thus'prov-ided a structure adapted to feed fibrous bearded grains, as described, possessing the features of advantage hereinbeiore enumerated asdeslrable and Wlnch 1s obviously-susceptible of modification in its form, proportion, and

arrangement of parts Without departing from the principle involved or sacrificing advantages.

Having thus claim any of its 1. In a distributer for grain-drills, a hop per, a revoluble distributerwheel, a flange :on

said Wheel and ribs formed on the interior of. said flange, the said ribs and flanges extend= ing up Within the hopper during-'the revolution of the Wheel, the studs-1 projecting from said Wheel'located betWeen-thefiange and thecenter of the Wheel, and upon the revolution? thereof adapted to agitate the grain Within the hopper, substantially as specified.

2. In a distributer for grainedrills, a hop-- interior side of the flange, said iWheel a'ndfi flange being located so that part ofrthe wheel and the fiangewillextend up within the hopper, studs projecting from the Web of said Wheel and also located to extendwithin the hopper during the revolution. of the 'Wheel, for the purpose specified.
